Los Angeles just rolled out some very straight-forward advice for transit riders with helpful titles like, "Heads-up or Headless?" and "Dismount or Dismembered."

Despite its car-centric reputation, L.A. actually has a growing public transit system, and with new trains running to the beach and the eastern suburbs, Metro Los Angeles put out a series of videos to educate residents about transit safety.

They do not...hold back.

The PSAs are set in the fictional town of "Safetyville," a place that contrary to its name is actually the scene of one horrific death after another.

"Uh oh," the narrator says seconds later as a lifeless body dangles from a wreckage. "Mike's joyriding days are over."

No one is spared from the horrors of public transit in Safetyville. For example, Jimmy — who appears to be a child — tries to flee a cop on his skateboard, runs over a pebble, and gets his leg ripped off by a passing train.

And Jack is literally decapitated.

"Uh oh, it looks like Jack took quite a spill," the narrator says as Jack's head bounces on the platform. "Never run to catch the train."

Though the videos depict brutal scenes, they come as L.A. increasingly becomes a place where cars, trains, and people intersect. For example, Metro's newly-expanded Gold and Expo lines — which run to the San Gabriel Valley and Santa Monica, respectively — have long sections that run at street level. And both of those lines have experiencedrun-ins with vehicles.

"We have a lot of new people, a lot of new riders, and a lot of new drivers that are engaging the trains for the first time," John Gordon, Metro's director of social media, told BuzzFeed News.

Gordon — who has also waged a "haiku battle" with San Francisco's BART system — said goal of the videos was to "create something that people would react to" and that the response has been "overwhelmingly positive."

"I think we hit the right tone between gruesomeness and levity," he added.
